Best Digital Signal Processing (DSP) Projects Using MATLAB

Summary

Have you ever wondered how the famous app namely my talking tom mimics your voice and return it in a cat voice? If yes then you might be interested in digital signal processing. The talking tom app is a basic example of DSP project, there are much more complex uses incorporating digital signal processing and it’s not limited to audio processing. Digital signal processing or abbreviated as DSP is a minor field of the vast topic namely signal processing. It is a fundamental of digital technology and is being extensively used in telecommunication and wireless communications industry.

By learning about DSP and implementing projects will open array of opportunities for yourself in the fields of speech compression, speech transmission, sound correction, weather, economic forecasting and also the budding field of seismic data processing. Before we get into the DSP projects or DSP project based on MATLAB let us first understand about some prerequisites of Digital signal processing.

What is digital signal processing (DSP) and its applications?

Digital signal processing implements the use of computers to perform various digital processing operations. DSP (Digital Signal Processing) is not only limited to computer but can also be done using processors specifically made for them namely digital signal processors. The output of digital signal processing obtained is usually a sequence of numbers which represents the analogue waveform samples of a variable in domains such as frequency, space and time. A digital signal is represented in the form of a pulse train.

Why DSP (Digital signal processing) is required?

Digital signal processing plays an important part in signal processing as it is known to provide high flexibility when it comes to using the same digital hardware for a variety of applications hence saving implantation costs.

If we compare the processing of digital signal with the conventional analog signal it is much better as analog electronics require different hardware for different application.

What is MATLAB Software?

It is a platform designed for technical people like engineers and scientists. MATLAB is made with MATLAB programming language commonly referred to as matrix language. The programming environment of MATLAB is designed to mimic the natural expression which is used in math.

Why MATLAB Software is very useful in digital signal processing?

MATLAB Software is well known in the digital signal processing industry thanks to its reputation of providing various signal processing products that are very helpful in analyzing signals. MATLAB can be used to acquire signals, measure them, transform them, successfully filter and provide visual data to a user. Even if you are not an expert in signal processing you can easily use signal processing tools of MATLAB and implement DSP projects.
